PUBLIC SAVINGS AT PT. BANK NTT (PERSERO) MAIN BRANCH KUPANG AND THE FACTORS AFFECTING THEM
No full textThe formulation of the problem in this study is (1) Whether the interest rate, inflation rate, and Regional Minimum Wage have a partial effect on the community\u27s savings at PT. Bank NTT (Persero) Kupang Main Branch Unit?; (2) How do interest rates, inflation and regional minimum wages affect the level of public savings at PT. Bank NTT (Persero) Kupang Main Branch Unit? The purpose of this study is to analyze the influence of interest rates, inflation rates, and regional minimum wages on the amount of savings, both partially and simultaneously. The analysis technique used is quantitative analysis using a multiple linear regression model. In this study, the smallest square regression approach (Ordinary Least Square) was also used. The results of this analysis show that simultaneously: interest rates, inflation rates, and regional minimum wages have a significant effect on savings. Meanwhile, partially, interest rates have a significant positive effect on savings, while inflation and the regional minimum wage have a negative but significant effect. The value of the determination coefficient was 0.115 which indicates that 15.5% of the variation in savings can be explained by all three variables, while the remaining 84.5% is influenced by other factors outside the model. The researcher suggested that Bank NTT needs to strengthen the innovation of savings products and digital financial services in order to be able to increase public fund collection.

Optimasi Hyperparameter Berbasis Bayesian dengan Optuna untuk Spectral Clustering - K-Means: Studi Kasus pada Dataset Leukemia CuMiDa
No full textLeukemia is one of the cancers with the highest mortality rate worldwide; therefore, identifying its subtypes is crucial to support accurate diagnosis and effective treatment. The analysis of high-dimensional gene expression data, such as the CuMiDa dataset, still faces major challenges due to overlapping patterns and limited sample sizes. This study proposes the application of Bayesian Optimization using Optuna to perform hyperparameter tuning on the Spectral Clustering – K-Means method to improve the clustering performance of leukemia subtypes. Four key parameters (n_components, affinity method, n_neighbors, and gamma) were optimized through 1,000 iterations. The best configuration was obtained at n_components = 5 using the Nearest Neighbors method with n_neighbors = 6. The resulting Spectral Embedding matrix was then grouped using K-Means. The results showed that this approach achieved a clustering accuracy of 92,19%, outperforming both K-Means and Hierarchical Clustering when applied separately. Heatmap visualization demonstrated that the optimized method effectively grouped samples with similar gene expression patterns. This study demonstrates that the combination of Spectral Clustering–K-Means and Bayesian optimization using Optuna can improve the clustering quality of complex gene expression data and open up broader opportunities for application in other bioinformatics studies
